Method for predicting skin sensitizing activity of compounds

ABSTRACT

Quinoline- and isoquinoline-based compounds exhibiting ATP-utilizing enzyme inhibitory activity, methods of using compounds exhibiting ATP-utilizing enzyme inhibitory activity, and compositions comprising compounds exhibiting ATP-utilizing enzyme inhibitory activity, are disclosed.

This application claims the benefit of U.S. Provisional Patent Application No. 60/577,224, filed Jun. 4, 2004; which is incorporated herein by reference for all purposes.

Protein kinases encompass a large family of functionally and structurally related enzymes that are responsible for the control of a wide variety of cellular processes including signal transduction, metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. In general, protein kinases control protein activity by catalyzing the addition of a negatively charged phosphate group from a phosphate-containing molecule such as cyclic adenosine monophosphate (cAMP), adenosine diphosphate (ADP), and ATP, to other proteins. Protein phosphorylation in turn can modulate or regulate the functioning of a target protein. Protein phosphorylation is known to play a role in intercellular communication during development, in physiological responses and in homeostasis, and in the functioning of the nervous and immune systems.

The unregulated phosphorylation of proteins is known to be a cause of, or associated with the etiology of major diseases, such as Alzheimer's disease, stroke, diabetes, obesity, inflammation, cancer, and rheumatoid arthritis. Deregulated protein kinase activity and over expression of protein kinases has been implicated in the pathophysiology of a number of important human disorders. Furthermore, genetic mutations in protein kinases are implicated in a number of disorders and many toxins and pathogens exert their effects by altering the phosphorylation of intracellular proteins.

ATP-utilizing enzymes, such as protein kinases, therefore, represent a broad class of pharmacological targets of interest for the treatment of human disease. Most human protein kinases can further be grouped into seven major groups based on the deoxyribonucleic acid (DNA) sequence homologies identified as CAMK (calcium/calmodulin-dependent protein kinases), AGC (including PKA (protein kinase A), PKG (protein kinase G), PKC (protein kinase C) kinases), CKI (casein kinases), CMGC (containing CDK (cyclin-dependent)), MAPK (mitogen activated), GSK3 (glycogen synthase) and CLK (CDC2-like) kinases), STE (homologs of yeast Sterile 7, Sterile 11, and Sterile 20 kinases), TK (tyrosine kinases), and TKL (tyrosine-kinase like).

The AGC protein kinase family includes AKT1, AKT2, AKT3, AURORA-A, MSK1, MSK2, P70S6K, PAK1, PKA, ROCK2, SGK1, PDK1, and RSK2 protein kinases. The CMGC protein kinase family includes the CDK1, CDK2/cyclinA, CDK2/cyclinE, CDK5, DYRK2, GSK3-α, GSK3-β, p38-α, p38-β, p38-δ, and p38-γ, and MAPK1 protein kinases. The CAMK protein kinase family includes the DAPK1, MAPKAPK2, MAPKAPK3, CHEK1, CHEK2, PRAK, c-TAK1, and PIM-1-kinase protein kinases. The TK protein kinase family includes the ABL1, CSK, FLT3, FYN, HCK, INSR, KIT, LCK, PDGFRR-α, LYNA, SYK, and SRC protein kinases. The STE protein kinase family includes PAK2 protein kinase.

Chronic and excessive production of the proinflammatory cytokines tumor necrosis factor-α (TNFα) and interleukin-1β (IL-1β) are thought to be important in the progression of many inflammatory and autoimmune diseases including Crohn's disease, psoriasis and rheumatoid arthritis. Activation of the p38 MAPK pathway by a variety of cellular stresses can be a key regulator in the production of TNFα and IL-1β and the p38 MAP kinase has been targeted as an important anti-inflammatory therapeutic target. p38 MAPK pathway regulated diseases include Crohn's disease, rheumatoid arthritis, psoriasis, inflammatory bowel disease, ulcerative colitis, sepsis, asthma, osteoporosis, chronic obstructive pulmonary disease, acute coronary syndrome, stroke, atherosclerosis, renal disease, Alzheimer's disease, and cancer. MAPKAPK2 is also a kinase in the p38 MAPK pathway and can be directly activated by p38 MAPK. Mouse knockout studies of MAPKAPK2 show a reduction in cytokine production and increase survival upon LPS challenge suggesting MAPKAPK2 can be a key regulator of the inflammatory response and can also be a potential target for anti-inflammatory therapy.

The identification and development of chemical entities that inhibit the functioning of ATP-utilizing enzymes is therefore of considerable interest.

Certain of those compounds were tested for protein kinase inhibitory activity according to the biological assays and definitions of protein kinase inhibitory activity as described herein.

Chemical entities described herein can be prepared by methods well known in the art. Chemical entities described herein can be prepared from readily available starting materials using the following general methods and procedures. It will be appreciated that where typical or preferred process conditions, such as, reaction temperatures, times, mole ratios of reactants, solvents, pressures, are given, other process conditions can also be used unless otherwise stated. Reaction conditions may vary with the reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures.

Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. Suitable protecting groups for various functional groups as well as suitable conditions for protecting and deprotecting particular functional groups are well known in the art. For example, numerous protecting groups are described in T. W. Greene and G. M. Wuts, Protecting Groups in Organic Synthesis, 3^(rd) Edition, John Wiley & Sons, 1999, and references cited therein.

Furthermore, chemical entities described herein can contain one or more chiral centers. Accordingly, if desired, such chemical entities can be prepared or isolated as pure stereoisomers, i.e., as individual enantiomers or diastereomers, or as stereoisomer-enriched mixtures. All such stereoisomers, and enriched mixtures thereof, are included within the scope of the present disclosure, unless otherwise indicated. Pure stereoisomers, and enriched mixtures thereof, can be prepared using, for example, optically active starting materials or stereoselective reagents well-known in the art. Alternatively, racemic mixtures of such compounds can be separated using, for example, chiral column chromatography, chiral resolving agents and the like.

General synthetic schemes and specific reaction protocols used to prepare compounds of the present disclosure are presented in the reaction schemes and Examples provided herein.

A compound of Formula 1 can be prepared as illustrated in Schemes 1 through 3 below. The 6-bromo-4-hydroxyquinoline or 7-bromo-1-hydroxyisoquinoline can be transformed into the halide IV (e.g. into the Cl via POCl₃) (Scheme 1). In addition, the chloro(iso)quinolines can be treated with an excess of iodide salt (e.g. NaI) to provide the iodo(iso)quinolines. Synthesis of I can occur by initial arylation of IV (where X¹=Cl) to provide V, followed by reaction of the appropriate amine/alcohol VII; or, initial reaction of IV (X¹=halo) with amine/alcohol VII to provide VI, followed by arylation. Alternatively, arylation can initially provide V′, which, following conversion to the corresponding halide, can be coupled with amine/alcohol VII to provide I. Arylation conditions include, but are not limited to, reaction of the bromide with the appropriate arylboronic acid or ester mediated by a metal catalyst. Numerous methods for aryl cross-coupling are known by those skilled in the art (Metal-Catalyzed Cross-coupling Reactions, VCH, Weinheim, 1998, 49-97; J. Organometallic Chem. 1999, 576, 147-168; Chem. Rev. 1995, 95, 2457; and references cited therein). Coupling of amine/alcohol VII with IV or V can be accomplished in a solvent or neat, at a temperature preferably between 20° C. and 200° C., and optionally with a base such as sodium carbonate or sodium hydride; in the case of utilizing alcohol VII, use of a strong base is preferred. The coupling may also be aided by microwave irradiation.

Amines of formula VII can be prepared as illustrated in Scheme 2. Nucleophilic displacement of 4-halonitrobenzene with the appropriately functionalized amine Q-H can provide the nitrophenyl intermediate VIII. Amines Q-H are commercially available or can be prepared via literature methods known by those skilled in the art. Alkylation of 3-phenylpyrrolidine or 4-phenylpiperidine can provide IX, which upon nitration, and separation of isomers if necessary, can provide nitrophenyl intermediate X. Reduction of the appropriate nitrophenyl derivative can provide the primary amine VIIa, which can also be alkylated to form the secondary amine VIIb. Amine alkylations illustrated in Scheme 2 can be accomplished, for example, by reaction of the amine with an alkyl halide or by reductive amination with the appropriate aldehyde under reducing conditions.

Alcohols of formula VII, where not commercially available, can be prepared as illustrated in Scheme 3. Reaction of an aryl bromide with the appropriate amine Q-H can be accomplished in the presence of a metal catalyst, such as palladium or copper (or their salts) to provide XI. Where the aryl bromide is substituted with an OMe group, demethylation can provide the phenol VIIc. In addition, certain compounds can be prepared from intermediate X via reduction of the nitro group to an amine, formation of the diazonium salt from the resulting amine, and hydrolysis of the diazonium salt to give phenols VIId.

In accordance with certain embodiments, chemical entities of the present disclosure exhibit ATP-utilizing enzyme inhibitory activity. Thus, one use of the chemical entities of the present disclosure includes the administration of at least one chemical entity of the present disclosure to a subject, such as a human. This administration serves to arrest, ameliorate, reduce the risk of acquiring, reduce the development of or at least one of the clinical symptoms of, or reduce the risk of developing or at least one of the clinical symptoms of diseases or conditions regulated by ATP-utilizing enzymes, such as, protein kinases.

For example, unregulated or inappropriately high protein kinase activity has been implicated in many diseases resulting from abnormal cellular function. Unregulated or inappropriately high protein kinase activity can arise either directly or indirectly, for example, by failure of the proper control mechanisms of a protein kinase, related, for example, to mutation, over-expression or inappropriate activation of the enzyme; or by over- or under-production of cytokines or growth factors also participating in the transduction of signal upstream or downstream of the protein kinase. In all of these instances, selective inhibition of the action of a protein kinase can be expected to have a beneficial effect.

According to certain embodiments, the present disclosure relates to methods of treating a disease regulated by at least one ATP-utilizing enzyme in a subject.

It will be understood, however, that the amount of the chemical entity administered will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual chemical entity administered, the age, weight, and response of the individual subject, the severity of the subject's symptoms, and the like.

For preparing solid compositions such as tablets, the principal active ingredient can be mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a chemical entity of the present present disclosure. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. The solid preformulation can then subdivided into unit dosage forms of the type described above containing from, for example, 0.1 mg to 2 g of the therapeutically effective chemical entity of the present present disclosure.

The tablets or pills comprising certain compositions of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer that serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials include a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

The liquid forms in which the compositions of the present disclosure may be incorporated for administration orally or by injection include aqueous solutions suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

In other embodiments, the dosage form can comprise a compound of the present disclosure coated on a polymer substrate. The polymer can be an erodible, or a nonerodible polymer. The coated substrate can be folded to provide a bilayer polymer drug dosage form. For example, a compound of the present disclosure can be coated onto a polymer such as a polypeptide, collagen, gelatin, polyvinyl alcohol, polyorthoester, polyacetyl, or a polyorthocarbonate, and the coated polymer folded to provide a bilaminated dosage form. In practice, the bioerodible dosage form can erode at a controlled rate to dispense the compound over a sustained release period. Representative biodegradable polymers include a polymer chosen from biodegradable poly(amides), poly(amino acids), poly(esters), poly(lactic acid), poly(glycolic acid), poly(carbohydrate), poly(orthoester), poly (orthocarbonate), poly(acetyl), poly(anhydrides), biodegradable poly(dehydropyrans), and poly(dioxinones).

In other embodiments, the dosage form can comprise a compound of the present disclosure loaded into a polymer that can release the compound by diffusion through a polymer, by flux through pores, or by rupture of a polymer matrix. The drug delivery polymeric dosage form can comprise a concentration of from 10 mg to 2,500 mg of the compound, homogenously contained in or on a polymer. The dosage form can comprise at least one exposed surface at the beginning of dose delivery. The non-exposed surface, when present, can be coated with a pharmaceutically acceptable material impermeable to the passage of the compound of the present disclosure. The dosage form can be manufactured by procedures known in the art.

The therapeutic composition in the dosage form can develop osmotic energy that can cause the therapeutic composition to be administered through an exit from the dosage form over a prolonged period of time, such as up to 24 hours, to provide controlled and sustained release of a compound of the present disclosure.

In other embodiments, the dosage form can comprise an osmotic dosage form comprising a wall surrounding a compartment, the wall having a semipermeable polymeric composition permeable to the passage of fluid and impermeable to the passage of a compound of the present disclosure contained within the compartment, a compound-containing layer composition in the compartment, a hydrogel layer composition in the compartment comprising an osmotic formulation for imbibing and absorbing fluid for expanding in size for pushing the prodrug or derivative composition layer from the dosage form, and at least one passageway in the wall for releasing the composition containing a compound of the present disclosure. This method can deliver a compound of the present disclosure by imbibing fluid through the semipermeable wall at a fluid imbibing rate determined by the permeability of the semipermeable wall and the osmotic pressure across the semipermeable wall causing the push layer to expand, thereby delivering the compound from the dosage form through the exit passageway to a subject over a prolonged period of time, such as up to 24 hours.

The hydrogel layer composition can comprise 10 mg to 1,000 mg of a hydrogel such as a polyalkylene oxide of 1,000,000 to 8,000,000 weight-average molecular weight, for example, a polyethylene oxide of 1,000,000 weight-average molecular weight, a polyethylene oxide of 2,000,000 molecular weight, a polyethylene oxide of 4,000,000 molecular weight, a polyethylene oxide of 5,000,000 molecular weight, a polyethylene oxide of 7,000,000 molecular weight and a polypropylene oxide of the 1,000,000 to 8,000,000 weight-average molecular weight; or 10 mg to 1000 mg of an alkali carboxymethylcellulose of 10,000 to 6,000,000 weight average molecular weight, such as sodium carboxymethylcellulose or potassium carboxymethylcellulose. The hydrogel expansion layer can comprise 0.1 mg to 350 mg of a polymer, for example, 0.1 mg to 250 mg of a hydroxyalkylcellulose of 7,500 to 4,500,00 weight-average molecular weight such as hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxybutylcellulose or hydroxypentylcellulose; 0.1 mg to 50 mg of an osmagent chosen from sodium chloride, potassium chloride, potassium acid phosphate, tartaric acid, citric acid, raffinose, magnesium sulfate, magnesium chloride, urea, inositol, sucrose, glucose and sorbitol; 0.1 to 5 mg of a colorant, such as ferric oxide; 0.1 to 1.5 mg of an antioxidant including ascorbic acid, butylated hydroxyanisole, butylated hydroxyquinone, butylhydroxyanisol, hydroxycoumarin, butylated hydroxytoluene, cephalm, ethyl gallate, propyl gallate, octyl gallate, lauryl gallate, propyl-hydroxybenzoate, trihydroxybutylrophenone, dimethylphenol, dibutylphenol, vitamin E, lecithin and ethanolamine; and 0.1 mg to 7 mg of a lubricant including calcium stearate, magnesium stearate, zinc stearate, magnesium oleate, calcium palmitate, sodium suberate, potassium laureate, salts of fatty acids, salts of alicyclic acids, salts of aromatic acids, stearic acid, oleic acid, palmitic acid, a mixture of a salt of a fatty, alicyclic or aromatic acid, and a fatty, alicyclic, or aromatic acid.

The wall is nontoxic and comprises a polymer such as a cellulose acylate, cellulose diacylate, cellulose triacylate, cellulose acetate, cellulose diacetate or cellulose triacetate. The wall can comprise 75 wt % (weight percent) to 100 wt % of the cellulosic wall-forming polymer; or, the wall can additionally comprise 0.01 wt % to 80 wt % of polyethylene glycol, or 1 wt % to 25 wt % of a cellulose ether including, for example, hydroxypropylcellulose or a hydroxypropylalkycellulose such as hydroxypropylmethylcellulose. The total weight percent of all components comprising the wall is equal to 100 wt %. The internal compartment can comprise the compound or composition of the present disclosure alone or in layered position with an expandable hydrogel composition. The expandable hydrogel composition in the compartment can increase in dimension upon imbibing the fluid through the semipermeable wall, causing the hydrogel to expand and occupy space in the compartment, whereby a pharmaceutical composition is pushed from the dosage form. The therapeutic layer and the expandable layer can act together to release of a compound of the present disclosure to a subject over time. The dosage form comprises a passageway in the wall that connects the exterior of the dosage form with the internal compartment.

As used herein, “passageway” refers to means and methods suitable for the metered release of the chemical entities of the present disclosure from the compartment of the dosage form. The exit means can comprise at least one passageway, including orifice, bore, aperture, pore, porous element, hollow fiber, capillary tube, channel, porous overlay, or porous element that can provide for the osmotic controlled release of a compound of the present disclosure.

Representative materials suitable for forming a passageway, or a multiplicity of passageways include a leachable poly(glycolic) acid or poly(lactic) acid polymer in the wall, a gelatinous filament, poly(vinyl alcohol), leach-able polysaccharides, salts, and oxides. A pore passageway, or more than one pore passageway, can be formed by leaching a leachable compound, such as sorbitol, from the wall. The passageway can possess controlled-release dimensions, such as round, triangular, square and elliptical, for the metered release of a compound of the present disclosure from the dosage form. The dosage form can be constructed with one or more passageways in spaced apart relationship on a single surface or on more than one surface of the wall. As used herein, “fluid environment” refers to an aqueous or biological fluid as in a subject, including the gastrointestinal tract.

A 1.06× Assay Buffer solution was prepared by combining 205.15 mL of 2× Master Buffer, and 181.92 mL of H₂O.

Assays to determine the kinase inhibitory activity of compounds of the present disclosure were performed using a Caliper HTS 250 microfluidics device, Greiner U-bottom assay plates, a Multidrop for transfer of reagents, and Biomek FX (AMNCBM03) software. Initially, 2.4 μL of a 1 mM solution of a test compound in 100% DMSO was added to a well of the Greiner U-bottom plate. A single Greiner U-bottom plate having 24×16 wells could include multiple test compounds. Next, 40 μL of 1.06× Assay Buffer was added to each well of the assay plate. Using the Biomek FX, 10 μL of 0.5 M EDTA was added by the span-8 to wells, indicated as 100% Control and 2.4 μL of 100% DMSO was added by the span-8 to wells, indicated as 0% Control. Using the Multidrop, 10 μL of 2.5× Enzyme Buffer, followed by 10 μL of 2.5× Substrate Buffer was added to each well of the assay plate. The total reaction volume in each well was 25 μL, and the concentration of the test compound was 10 μM. The assay plate was incubated for 2.5 hrs at 20° C. to 22° C. After the incubation period, using the Multidrop, 45 μL of 1.55× Termination Buffer was added to each well of the assay plate to stop the reaction. The inhibition of the ATP-utilizing enzyme, such as a particular protein kinase, was determined by measuring the ratio of the peptide substrate to phosphorylated product for each well of the assay plate using the Caliper HTS 250 system.

Compounds exhibiting an activity for a particular target ATP-utilizing enzyme greater than six-sigma from the mean activity for the population of predominately inactive compounds for the same target ATP-utilizing enzyme were considered to be active. The use of six-sigma statistical limits represents a conservative method for declaring potential hits among targets. The six-sigma activity, as well as the mean population activity, can be different for each target enzyme. This method has an expected false positive rate, from an in-control measurement process, of one in one million. Compounds were considered to show selectivity between a primary target and one or more other targets if the activity (e.g. % inhibition, IC₅₀, K_(i), EC₅₀, etc.) for that compound against the primary target was significantly different than that for the other target(s) within the error of the activity measurement.
